Openldap administration

Hey all, first off, I must admit: great work so far =)
I have a question though, how would it be possible to administer the ldap db remotely with tools like
ApacheDirectory Browser?
I tried already with the admin account, but every attempt to modify the schema fails with "no write access to parent"
I would like to delete a machine account, is there any other way to achieve this, without fiddling with ldap?

kr, marcel
